Abstract: Embedded application systems have developed vigorously in the Internet era, but network application security issues have also arisen. TrustZone technology is a system-level security framework specially built by ARM for electronic consumer products in this scenario that can resist various possible attacks. It is a security technology unique to ARM processors. Focusing on the principles and characteristics of ARM TrustZone, this paper focuses on analyzing the system security protection technology based on TrustZone, comparing this technology with other system security protection technologies, and further exploring its advantages and disadvantages. Finally, combined with the current security issues in the field of trusted execution environments, the future development of this technology is prospected.
